Frequently asked questions
Can I add spray foam to existing walls?
Spray foam is best installed when wall cavities are open during construction or a major remodel. For closed walls, we'll talk through other options that may make sense for your situation.
Open-cell or closed-cell for walls?
Open-cell is a common choice for interior wall cavities — it's cost-effective and excellent at sound dampening. Closed-cell is preferred where higher R-value, moisture resistance, or structural rigidity matter, like exterior walls in pole barns or below-grade walls.
Do you do garage and pole barn wall insulation?
Yes — garages, pole barns, shops, and agricultural buildings are a regular part of our work.
